Hi,
The errors..
HTTP Web Server: Couldn't find design note - css/tags.css [/appl/sstvideo.nsf/css/tags.css]
HTTP Web Server: Couldn't find design note - addanevent.js [/appl/sstvideo.nsf/addanevent.js]
HTTP Web Server: Lotus Notes Exception - File does not exist [/opentv15.nsf/favicon.ico]
I know about these, they are missing design elements. They are not required, but I left them in the HTML Header so I need to remove them, that should not cause the issue you have.
I have not tested Open.TV on 8.5 yet.
Are both servers running https? I do not have https enabled on my development server…
